open-in-new Find other Temperature switches

Description

The TMP302-Q1 family of devices is a temperature switch in a micropackage (SOT563). The TMP302-Q1 family of devices offers low power (15 µA maximum) and ease-of-use through pin-selectable trip points and hysteresis.

These devices require no additional components for operation; they can function independent of microprocessors or microcontrollers.

The TMP302-Q1 family of devices is available in several different versions with trip points from 50ºC to 125ºC in increments of 5ºC (see the Device Comparison Table).
